SEO：.SEドメインで動作するwhoisサーバですか？

Question

私は小さなドメインチェッカーを開発していると私は.SEを動作させることはできません。

public string Lookup(string domain, RecordType recordType, SeoToolsSettings.Tld tld) 
{ 
    TcpClient tcp = new TcpClient(); 
    tcp.Connect(tld.WhoIsServer, 43); 
    string strDomain = recordType.ToString() + " " + domain + "\r\n"; 
    byte[] bytDomain = Encoding.ASCII.GetBytes(strDomain.ToCharArray()); 
    Stream s = tcp.GetStream(); 
    s.Write(bytDomain, 0, strDomain.Length); 
    StreamReader sr = new StreamReader(tcp.GetStream(), Encoding.ASCII); 
    string strLine = ""; 
    StringBuilder builder = new StringBuilder(); 
    while (null != (strLine = sr.ReadLine())) 
    { 
     builder.AppendLine(strLine); 
    } 
    tcp.Close(); 
    if (tld.WhoIsDelayMs > 0) System.Threading.Thread.Sleep(tld.WhoIsDelayMs); 
    return builder.ToString(); 
} 

私はWHOISサーバ私は保つwhois.nic-se.seとwhois.iis.seプットを試してみました取得：

"domain google.se" not found. 

編集：

を私は他の結果とUTF8に変更しようとしました。

私はsysinternalsからwhoisを使用しようとすると、正しい結果が得られますが、SE.whois-servers.netを使用しなくても自分のコードでは得られません。私のMac上でwhois google.seを行うとき

/ニールス

Answer 1

私はついにそれを解決しました。 Wiresharkの使い方

、私はSysinternalsのWHOISは、 "DOMAIN" の部分を追加していないことを見た：

文字列strDomain = recordType.ToString（）+ "" +ドメイン+ "\ rを\ n" は、

（recordType.ToString == "DOMAIN"）。

私がそれを取り除いたとき、それは機能しました！

うーん、私は次を得る：

は、だから、おそらくあなたのコードです。おそらくUTF8のような非ASCIIエンコーディングでリクエストを行う必要がありますか？

Answer 3

あなたのコード理由ではないに見もせず：あなただけがRIPEたい場合

例

http://balexandre.com/verifyDomain.aspx @

これはpar.se

IP Found: 
- 193.13.249.142 

Host name: 
- parweb1.par.se 
Aliases: 
none 
IP address list: 
- 193.13.249.142 

のために、あなたを与えるだろうIPのの情報また

ボタンイベント

protected void btnCheck_Click(object sender, EventArgs e) 
{ 
    DomainCheck domain = new DomainCheck(); 
    string ip = domain.GetIPFromDomain(txtDomain.Text.Trim()); 

    litResponse.Text = String.Format(
          "IP{0} Found:<br/> - <strong>{1}</strong><br/>{2}", 
          ip.Contains(",") ? "'s" : "", 
          ip.Replace(",", "<br/> - "), domain.VerifyIP(ip)); 
} 

DomainCheckコードは

{テストするには、ip}テスト
